fh
File handle (handle).

.SH INPUT PARAMETER
.ft R
.TP 1i
buf

Fortran only: Error status (integer).

.SH DESCRIPTION
.ft R
MPI_File_write_ordered_end is the ending part of a split collective routine that must
be called by all processes in the communicator group associated with
the file handle
.I fh.
MPI_File_write_ordered_end returns the number of elements written into the file associated with
.I fh
in
.I status.

.SH NOTES
.ft R
All the nonblocking collective routines for data access are "split" into two routines, each with _begin or _end as a suffix. These split collective routines are subject to the semantic rules described in Section 9.4.5 of the MPI-2 standard.

.SH ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI::Exception object.
.sp
Before the error value is returned, the current MPI error handler is
called. For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
